Why does the new tax year start on the 6th and not the 1st April?
Happy new year. Tax year that is.
Yes the new tax year starts on the 6th April but have you ever wondered why it starts on the 6th and not the 1st?
Initially, and we are talking Middle Ages here, the tax year began on the Feast of Annunciation (known as Lady Day) which is the 25 March. The church was an important part of most people’s lives and naturally the Church Calendar was followed. We still see traces of this today in rental contracts which traditionally use Lady Day as one of the quarter days for collection, the others being 24th June (Midsummers Day), 29th September (Michaelmas) and 25th December (Christmas Day).
However, in 1752 the Julian calendar was switched to the Gregorian calendar which contained a mismatch because of the recognition of Leap Years which resulted in the new tax year starting on the 6th April.
No government has since seen fit to change the date to the first as it would mean a notional loss of 5 day’s worth of tax revenue in the eyes of the voting public.
